摘要

Two aspects of pavement surfaces that influence traction during wet weather are macrotexture, which provides both temporary storage volume and drainage channels, and microtexture on the aggregate, which provides direct tire contact. Grooving of slippery pavements has increased macrotexture depths and sharply reduced the incidence of wet weather accidents without a commensurate rise in the friction number as measured with the standard ribbed test tire. Research has sought to use the different responses of these two tires to identify textural properties of safe pavements and to provide quick and accurate assessments of pavement texture. The project evaluated outflowmeter time, sand patch mean texture depth, and friction test data from both the smooth and ribbed tires on bituminous surfaces in West-Central Indiana in Autumn 1987. On the basis of data from only eleven sites, significant correlation between friction data and both mean texture depth and outflowmeter time were obtained. It is recommended that the data base be expanded to establish the relationships over a fuller range of pavements.
